Abstract
The utility model relates to an energy-saving noise-elimination check valve. The energy-saving noise-elimination check valve comprises a valve body, a valve rod, a valve clack, a spring and a lining. A through hole is arranged in the middle of the lining. A valve clack sealing ring is arranged between the valve rod and the valve clack. The lining is fixedly connected with the valve body through a bolt. The two sides of the valve rod near the end face of the valve body are respectively fixedly connected with a first guide copper sleeve and a second guide copper sleeve. One end of the first guide copper sleeve is arranged in the valve body and the other end of the first guide copper sleeve is arranged outside the valve body and is provided with a guide copper sleeve closing ring. The outer surface center of the second guide copper sleeve is arranged in the through hole of the lining. The two sides of the second guide copper sleeve extend to the outside of the through hole of the lining. One end near the end face of the valve body of the second guide copper sleeve is provided with a guide copper sleeve closing ring. The energy-saving noise-elimination check valve has the advantages of ensuring the energy-saving effect and sealing, and being easy to repair when damaged by adopting the structure.
Description
Technical field
The utility model relates to a kind of energy-saving damping safety check.
Background technique
Damping check valve refers to rely on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and its Main Function is to prevent that medium from flowing backwards, preventing water pump and drive motor counter-rotating.The protection pipe network normally moves.Damping check valve mainly comprises valve body, guide sleeve, valve rod, flap, spring, lining, existing damping check valve, cast iron valve body targeting part wear resistant corrosion resistant is poor, valve rod increases at valve body guide sleeve operation a period of time post gap, guidance quality reduces, noise increases, and energy-saving effect descends, and valve rod is stuck when serious; Flap and valve rod are an integral body, in case valve rod and flap perpendicularity are processed with deviation, can't guarantee sealing; Lining adopts with valve body and is threaded, in case spring can't be used by sludge blockage, when breaking down, if do not have professional tool with regard to bad replacing, is not easy to maintenance.
The model utility content
The purpose of this utility model is that solution cast iron valve body targeting part wear resistant corrosion resistant is poor, and after operation a period of time, guidance quality reduces, the problem that energy-saving effect descends; If valve rod and flap perpendicularity are processed with deviation, the problem that sealing can reduce; Be not easy to the problem of keeping in repair when breaking down.
The technical solution adopted in the utility model is: a kind of energy-saving damping safety check, comprise valve body, valve rod, flap, spring, lining, the central authorities of lining are provided with through hole, be provided with valve clack sealing ring between described valve rod and flap, described lining is fixedly connected with bolt with valve body, described valve rod two ends are fixed with respectively the first guide copper sleeve and the second guide copper sleeve near the valve body end, and an end of the first guide copper sleeve is positioned at valve body, the other end is positioned at outside the valve body and be provided with the guide copper sleeve back-up ring; The second guide copper sleeve outer surface central authorities are positioned at outside the through hole of lining, the through hole that lining is stretched out at two ends, and described the second guide copper sleeve is provided with the guide copper sleeve back-up ring at the end near the valve body end.
The beneficial effect that the utility model adopts is: after having adopted this structure, valve rod is provided with guide copper sleeve, has improved wear resistance and corrosion resistance, can because long-time the use causes guidance quality to reduce, not guarantee energy-saving effect; Be provided with valve clack sealing ring between valve rod and flap, because seal ring is flexible, valve rod and flap can not cause sealing to reduce because of the deviation of processing, guaranteed sealing; The bolt that only need pull down lining when breaking down just can take out spring and flap, and need to by professional tool, not be convenient to maintenance.
Description of drawings
Fig. 1 is the utility model schematic representation.
Shown in the figure: 1 valve body, 2 valve rods, 3 flaps, 4 springs, 5 linings, 6 valve clack sealing rings, 7 first guide copper sleeves, 8 second guide copper sleeves, 9 guide copper sleeve back-up rings, 10 bolts.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, a kind of energy-saving damping safety check, comprise valve body 1, valve rod 2, flap 3, spring 4, lining 5, the central authorities of lining 5 are provided with through hole, 3 of described valve rod 2 and flaps are provided with valve clack sealing ring 6, described lining 5 is fixedly connected with valve body 1 usefulness bolt 10, and the end that close valve body 1 end, described valve rod 2 two ends is fixed with respectively the first guide copper sleeve 7 and the second guide copper sleeve 8, the first guide copper sleeves 7 is positioned at valve body 1, the other end is positioned at outside the valve body 1 and be provided with guide copper sleeve back-up ring 9; The second guide copper sleeve 8 outer surface central authorities are positioned at through hole, the two ends of lining 5 and stretch out outside the through hole of lining 5, and described the second guide copper sleeve 8 is provided with guide copper sleeve back-up ring 9 at the end near valve body 1 end.
After the utility model had adopted said structure, valve rod was provided with guide copper sleeve, had improved wear resistance and corrosion resistance, can because long-time the use causes guidance quality to reduce, not guarantee energy-saving effect; Be provided with valve clack sealing ring between valve rod and flap, because seal ring is flexible, valve rod and flap can not cause sealing to reduce because of the deviation of processing, guaranteed sealing; Lining is fixedly connected with bolt with valve body, and the bolt that only need pull down lining when breaking down just can take out spring and flap, and need to by professional tool, not be convenient to maintenance.
